Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. [ 1 ] A certain amount of binding is obtained through the use of carefully selected interlocking stones. Dry stone construction is best known in the context of stone walls ...
Class of water damage is determined by the probable rate of evaporation based on the type of materials affected, or wet, in the room or space that was flooded. Determining the class of water damage is an important first step, and will determine the amount and type of equipment utilized to dry-down the structure. [7] Class 1 - Slow Rate of ...
Dimension stone is natural stone or rock that has been selected and finished (e.g., trimmed, cut, drilled or ground) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to ...
Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.

Small granite pillars have failed under loads that averaged out to about 1.43 ⋅ 10 8 Newtons/meter 2 and this kind of rock has a sonic speed of about 5.6 ± 0.3 ⋅ 10 3 m/sec (stp), a density of about 2.7 g/cm 3 and specific heat ranging from about 0.2 to 0.3 cal/g °C through the temperature interval 100-1000 °C [Stowe pages 41 & 59 and ...
Damp (structural) Detail showing some of the causes of damp penetration. Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. A high proportion of damp problems in buildings are caused by ambient climate dependent factors ...
